  <p>
   We can prove that the following assertions are both true:
   <ul>
    <li>If {0} then {2}
    <li>If {1} then {2}
   </ul>
   Because one of the assumptions "{0}" or "{1}" is true and the conclusion is the same in both cases it follows that the conclusion must be true: <b>{2}</b>.<br/>
   Each assertion is proven by one or several dynamic forcing chains, each potentially consisting of multiple sub-chains.<br/>
   This solving technique is related to 3D Medusa.
